Proxy auto-configuration (PAC)

We recommend that for all web browsers that will connect directly to the cloud proxy, you use the PAC file configured within the cloud service. This file contains a number of global settings and allows you to enter exclusions of your own (for example, intranet sites) that should not use the cloud service proxy (see Proxy bypass).

The exact mechanism for configuring a user’s browser to use the PAC file depends on the browser and your network environment. For example, if you are using Microsoft Active Directory and Internet Explorer or Mozilla Firefox, you might want to automate the process by using group policies.

There are a number of different URLs you can use to retrieve a service-generated PAC file. The URL you choose determines which version of the PAC file is retrieved.

Different variants of the PAC file are suited to different network environments.
